HAND WEAVING LOOM 2 Sheets-Sheet 2 Filed April 6, 1959 Fiy- 3 UnitedStates Patent Office 3,032,971 Fatented May I, 1962 3,032,071 HANDWEAVLNG LOOM Toshiko Kokonoe, 204 Kamiikegami-cho, Ota-ku, Tokyo-t0,Japan Filed Apr. 6, 1959, Ser. No. 804,170 1 Claim. (Cl. 13933) Thisinvention relates to a hand Weaving loom, and more particularly to a newand improved basic loom frame for hand weaving.

It is an object of this invention to provide a basic loom frame for handweaving which is of low weight, small size, is conveniently portable,and, at the same time, can be made suitable for weaving hand wovenfabrics of a wide variety of materials, of any desired width, and of anydesired length by joining any number of similar basic loom frames in thetwo orthogonal directions in the plane of the original basic loom frame.

The details of this invention together with the abovesaid object, otherobjects, and advantages of this invention will be more clearly apparentby reference to the following detailed description of practicalembodiments of the invention when taken in connection with theaccompanying illustrations, in which;

FIG. 1 is a perspective view showing one embodiment of the presentinvention;

FIG. 2 is a perspective View of another practical embodiment of theanchoring device for the warp.

FIG. 3 pertains to FIG. 1 and is a diagrammatic persspective viewindicating a portion thereof in the process of hand weaving.

Referring to FIG. 1 of the drawings, reference symbol A designates aprincipal basic loom frame constructed in the form of a lattice byfastening a plurality of base boards 1 at certain intervals of space tocross-members 2 and 2a each of which has bolt holes 20 at both of itsends for joining. Reference symbol B designates a supplementary basicframe constructed in the form of a lattice by fastening a plurality ofbase boards 1a at intervals of space to cross-member 2b andsupplementary cross-member 3, each of which has bolt holes 20 at both ofits ends for joining. Frames A and B are connected on their reversesurfaces by hinges 4 and are so constructed that they can be foldedmutually back-to-back. On the upper surface of each of the cross-members2, 2a and 2b is fastened, by adhesion, an elastic piece, for example, arubber strip 9 on which the warp threads may be held by means of holdingpins, for example, thumb tacks 10. In addition, a plurality of warpanchoring pins 11 are imbedded securely on one vertical side in thelongitudinal direction of each of the cross-members 2, 2a, and 2b of theframes A and B. These anchoring pins 11 may be imbedded, as indicated inFIG. 2 in a base piece 13 having L-shaped key holes 15 so that, byfitting these key holes 15 of the base piece 13 to protruding knob 14affixed to the cross-member 2, the anchoring pin part can be installedand removed at will. Reference numeral designates an angle shapedconnecting piece having left and right holes 5a and 5b in its verticalportion for connecting with the cross member 2a and left and right holes50 and Ed in its horizontal portion for connection to base board 1a, asindicated in FIG. 1. The connecting piece 5 can be fastened to thecross-member 2a by means of bolt 8 and nut 7, said bolt being passedthrough the connecting bolt hole 20 of the cross-member 2a and throughthe hole 5a of the connecting piece 5. In a similar manner, theconnecting piece 5 can be fastened, through the other hole 512, to thecross-member 2a of a unit basic frame to be connected adjacently.Further, the connecting piece 5 is fastened to the base boards In bymeans of screws inserted through holes 50 and 5d and into correspondingholes prepared in the base boards 1a.

Moreover, connecting pieces similar to the connecting piece 5 can beattached to the crossmembers 2 and 2b. However, by the use of simpleconnecting pieces 16 which have left and right connecting bolt holes 17,the aforesaid cross-members may be connected to adjacent basic frames bymeans of bolts 8 passing through the said holes 17 and nuts 7. In theaforementioned manner, by means of connecting pieces 5 and 16, adjacent,unit basic frames may be connected additively so that the entireassembly, may be utilized in weaving products of broad width. Moreover,if the total length of the basic frame A together with a supplementarybasic frame B is too short for the intended use, connecitng ferrules 12as indicated in FIG. 1 may be fitted onto the ends of base boards 1aand, by means of the ferrules 12, another unit basic frame of similarkind can be connected in the longitudinal direction. It is to beunderstood that, for the aforementioned means of connection, any otherconnection means may be so utilized that the same function is therebyfulfilled.

The basic frame of the foregoing description is used as illustrated inFIG. 3, as one example, in which the warp strips 24 and 25 are passed,respectively, through the upper openings 23a and 23b of the diamondshaped frame operative pieces 23; the ends of the Warp strips may beanchored on the pins 11 or are anchored on the elastic pieces 9 of thecross-members 2, 2a and 21) illustrated in FIG. 3; upper rods 20 andlower rods 21 are passed, respectively, through the upper circular holes230 and lower circular holes 23d of the operative pieces 23, each pairof said rods 20 and 21 defining a row of alternate operative pieces anda row of operative pieces intermediate the alternate operative pieces,both said rows substantially parallel to said end cross member 2; andthe aforesaid parts are held above the basic frame on the rod supports19 supported in turn by the support bases 18. In the weaving operation,the upper openings 23a of the operative pieces through which the warpstrips-24 have been passed and the upper openings 23b of the operativepieces through which the Warp strips 25 have been passed are alternatelylifted up, thereby vertically separating the alternate warps 24 and 25so that the strips 24 are above and then below the strips at each changeof strip position 25. A scale 22 is flatly inserted between theseparated warp strips and then rotated to a vertical position to holdthe strips the width of the ruler apart. The woof is passed through theseparated strips by means of a bobbin 26, thereby effecting the weavingby progressive steps after each passage of the woof the scale 22 isrotated and flatly withdrawn to allow the warps to be verticallyshifted.

As apparent in the description stated above, by this invention, elasticpieces are affixed adhesively to the upper surfaces of the cross-membersof the basic frame. Accordingly, the anchoring thereon of the warpstrips by means of pins and the removal of the said strips is extremelyeasy. Consequently, it is possible to anchor and remove the warp stripsreadily and freely to and from any desired position. Moreover, becausethe warp an choring pins are provided on the side surface of thecross-members, the afiixing of the warp strips at fixed positions isalso convenient. Therefore, by this invention it is possible to obtain adevice which has excellent characteristics as a basic frame for handweaving, the vital requisite of which is simplicity and convenience.Moreover, because by this invention, the basic frame is made in the formof an integral, single unit of lattice form of light weight and, inaddition, is of such a construction that additive extension in either ofthe orthogonal directions in its plane is convenient, the said basicframe is conveniently portable and remarkably convenient for handweaving woven fabrics of any length and width.

While several and various changes and modifications can be made in theabove described details without departing from the spirit and scope ofthis invention, it is to be understood that the invention is not to belimited to the details described herein except as set forth in theappended claim.
